YUV

YUV refers to a colour transmission system where the LUMA is encoded separately from two colour components, U and V

It is often used in computing to refer to any such non-RGB system. It is now used more or less interchangeably with Y’CbCr (and YPbPr – the analogue version of Y’CbCr).

Although YUV has a history in the development of analogue colour television and there are technical differences in the calculation and scale of the colour components, for practical purposes YUV, Y’CbCr and YPbPr can be considered the same.
